“I invoke my right.”, “hindi ko alam.”
And on her question about Napoles got rich so quick without going through college:

“I invoke my right. There is already a case at the Ombudsman.”
Santiago:“Ilan ang bahay mo?”

Napoles:“I only have three.”
Santiago: “Do you have 30 vehicles?”

Napoles:“Hindi po. I have seven.”
Santiago:“Do you have 415 accounts with 17 different banks?”

Napoles:“I invoke my right, pero hindi po ganoon karami.”

Santiago: “You claim to be a Catholic, do you know the ten commandments? That you should not steal?”
Napoles : no answer
Santiago:“That you should not tell a lie? Ngayon pa lang, nagsisinungaling ka na e.”

“At 9:37 p.m. on August 28, Janet Napoles surrendered to President Aquino,” Presidential Spokesman Edwin Lacierda said in a statement.

“The President turned her over to the custody of Interior and Local Government Secretary Mar Roxas and Philippine National Police Director-General Alan Purisima for processing and booking,” Lacierda said.

Pre-empted

The move pre-empted the National Bureau of Investigation Special Task Force that earlier got a hot tip on the Napoles’ whereabouts and was on its way to serve her warrant of arrest.

Napoles specifically asked through her lawyer, Lorna Kapunan, that she be brought to Camp Crame and not to the NBI.

Aquino motored to the PNP national headquarters to accept the surrender of Napoles and turned her over to Roxas.
